Burt Bucks from Raising Hope
The well-intentioned Burt Bucks was a great way for the Chances to get to know their neighbors while exchanging one good deed for another. In the end, too much of a good thing turns bad, and everyone’s left overstuffed with lobsters and too many knitted hats. Dollar Conversion: one market-priced lobster.

Paddy’s Bucks from It’s Always Sunny in Philadelphia
Dennis and Mac hand out Paddy’s Bucks to drifters loitering outside of the bar as a way to get them to buy drinks at the pub. They spend a ton of real cash on creating fake Paddy’s Bucks, but you’ve gotta spend money to make money, right? That’s how the whole self-sustaining economy thing works, right? Well, no, not right. Dollar Conversion: -$100

Schrute Bucks & Stanley Nickels from The Office
Created as a way to encourage good behavior for extra lunchtime, Dwight’s plan is foiled with the invention of Stanley Nickels, and neither currency prevails.Dollar Conversion: one Schrute Buck is 1/100th of a cent, but there is no comparison for Stanley Nickels, as its namesake said, it’s like the “ratio of unicorns to leprechauns.”

Federation Credits from Star Trek
Since dollars will not exist in the future, these credits are used exclusively for the elite. Uhura offered to buy a tribble for ten credits once.Dollar Conversion: $1.03, according to this.

Kittens from Buffy the Vampire Slayer
Used in Kitten Poker, demons bet with those adorable meowing bundles. Dollar Conversion: priceless.

Nadia Chaudhury would gladly exchange her life savings for all the kittens and all the Tribbles.

If you're going to mention Star Trek, you have to mention the episode where Kirk, Uhura, and Chekov are kidnapped and forced by disembodied brains to fight as gladiators so the brains can bet 'quatloos' on them.

Didn't the Janitor on Scrubs have some kind of alternate currency. I'm a little scared to google "janitor money".

The kittens gag remains one of the funniest things I've ever seen on television.
